LASER SPARK PLUG Russian patent published in 2018 - IPC F02B19/12 F02P23/04 H01T13/40 

FIELD: power engineering.

SUBSTANCE: invention relates to power machines, specifically to laser spark plugs with an ignition cell, and can be useful in transport and heat power engineering. Purpose of creating an invention corresponding to the achieved technical result is to extend the service life of the laser spark plug by preventing contamination of the optics and the laser beam outlet. Solution of these problems is achieved in a laser spark plug, containing housing, insulator, microchip laser installed in the cavity inside insulator, vacuum tube connected to it, optical window, focusing lens, pre-chamber with a cylindrical and conical cavity, washer with a hole - between the optical window and the pre-chamber, and target installed in one of the cavities of the pre-chamber, several outlets, entering into the conical cavity, in that the target is mounted on the axis with the possibility of rotation and the working blades of the aerodynamic turbine are fixed to the shaft.

EFFECT: technical result is an increase in the service life of the laser spark plug by preventing contamination of the optics and the laser beam outlet.
